Description

Railway level-crossing

The present invention relates to a kind of railway level-crossing, wherein, the runway at road junction place by expert guidance tape and outside carriageway plate constitute, in these carriageway plates have cantilever shalving be connected on the rail of track with thereon along the spacing between the carrying rib of the rail raised edges of extension, by these carrying ribs, interior carriageway plate is flexible, be supported on the flange of rail under the interlocking of the section bar supporting mass of making by rubber or plastics, and its side support is on the web of the rail, the top is bearing on the rail head, simultaneously, for the carrying wing that supports interior carriageway plate helps, being provided with cross section on rail is the lower support body of dihedral, one personal share of lower support body is close on the flange of rail, and its another thigh is positioned at by the web of the rail, being provided with cross section in addition is the upper support body of dihedral, the one personal share is close to the downside of rail head, and its another thigh is positioned at by the web of the rail, the carrying rib of carriageway plate is fitted on the thigh that is positioned at the other supporting mass of the web of the rail, its downside is installed on the thigh of the lower support body that is positioned on the flange of rail, in addition, set downside from carriageway plate to the step of the downside that carries rib forms a contact surface vertical with the plate face on the installation site of the carrying rib of carriageway plate, be close to the flange of rail the lower support body the thigh avris be fitted on the above-mentioned contact surface, outer carriageway plate has the carrying rib equally in its edge towards track at least, same these carrying ribs that lean on are bearing in outer carriageway plate on the rail, and the outer rim of outer carriageway plate is bearing on the matrix.

On carriageway plate, acting on the level and vertical impact force that cause by rail vehicle.Owing on the bearing of the carrying rib of the guidance tape on the flange of rail, be provided with the lower support body of elasticity dihedral, weakened the impact force that is delivered on the rail.At this moment, supporting mass is just by the short time elastic compression.

In a known level crossing of the above-mentioned type, the downside of the carrying rib of interior guidance tape is designed to be parallel to the plane of plate face, and be placed in the upside of the thigh that is positioned at the flange of rail that its cross section is the lower support body of dihedral, the extended surface of guidance tape in the upside of this strand is in substantially parallel relationship to; Load that constitutes by the weight of interior guidance tape and the load that causes by the carriage load on the guidance tape in vertical the acting on by the upside of thigh by being positioned at the downside of supporting rib, and in the extended surface and being delivered to of guidance tape is parallel to equally in being parallel to guidance tape on the extended surface on the flange of rail lower support body thigh, and continue to be delivered to the flange of rail of the rail of track from this; Act on the horizontal force on the guidance tape in the level crossing from the outer rim of the carrying rib of interior guidance tape through being positioned at the thigh of the other lower support body of the web of the rail, perhaps the upper support body strand is delivered on the web of the rail; Cross section is that the lower support body of dihedral is owing to its downside that is in substantially parallel relationship to the supporting rib that the guidance tape face extends has quite thick thigh, simultaneously, the downside that is positioned at the supporting mass thigh on the flange of rail must have one with the quite consistent shape of the upside of the flange of rail, therefore just must be for the different cross-sections of the rail, even its shape has only minimum deviation also to need to use supporting mass with its coupling, thereby can be to produce sizable crimp on the supporting mass of dihedral also at cross section, supporting member is installed by the following method inwall that reclining, that is to say the avris of the lower support body thigh that is positioned on the flange of rail is fitted on the contact surface of the guidance tape vertical with the guidance tape face, and the outer rim of carrying rib is fitted on the inboard that is positioned at the other supporting mass thigh of the web of the rail; The web of the rail load that causes from the interior guidance tape power on the web of the rail that is delivered to is quite big, this point is very disadvantageous, because sizable strand thickness is arranged, interior guidance tape can be only than the width of rail gauge more greatly, that is to say, width from the outer rim of a carrying rib to the interior guidance tape that records of outer rim of another carrying rib is only than the most much 1cm of gauge width, because carrying rib downside is parallel to the guidance tape face, the thigh of the elastic support body at known road junction has above-mentioned thickness, because the following engagement of carrying rib body rail head is quite little, following engagement has stoped interior guidance tape to produce undesirable moving up like this; With regard to known situation, the width of side plane under the guidance tape carrying rib just can be implemented in transmitted load on the flange of rail thus in the quite thick thigh of supporting mass had also limited and has been arranged on, and this is disadvantageous equally; The shape of cross section of this carrying rib also makes reinforcing bar should not be installed in the guidance tape, and the shape of cross section of above-mentioned carrying rib is determined by plane guidance tape plate face, that be arranged on the carrier rib downside in being parallel to.

Also disclose a kind of railway level-crossing, in this kind road junction, the carriageway plate bearing on the flange of rail is designed to be different from above-mentioned level crossing, just have thin, that make by rubber or its similar item, only be arranged on backing plate on the flange of rail.So Bao backing plate does not have and obviously reduces the effect impacted, because so Bao backing plate almost is can not be compressed.Because backing plate is thin, the shape of carrying rib and backing plate must be coincide with the shape of rail.So just can not be used for difform rail.

The object of the present invention is to provide the railway level-crossing of the above-mentioned type, this level crossing is because its simple structure and easy installation property, and eliminated aforesaid drawbacks, particularly, the characteristics of power and loading transfer therein are installed in bearing on the rail in view of having guaranteed to constitute in orbit the road Board position of runway and guidance tape.

The railway level-crossing of aforementioned type designed according to this invention, it is characterized in that, the approximate upside that is parallel to the flange of rail of downside of the carrying rib that is positioned at cross section on the flange of rail and is the upside of dihedral lower support body thigh and install thereon, at least at the downside that is positioned at the lower support body thigh on the flange of rail, also can numerous, arranged side by side deep trouths be set in each side of remaining lower and upper supporting mass towards rail.Purpose by the above-mentioned proposition of this structure fine adaptation of energy.By being that the deep trouth arranged side by side that is provided with on the lower support body of dihedral can make the surface of supporting mass have good deformation characteristic at cross section, this deformation characteristic can make the thigh of supporting mass adapt to difform, and a thick thigh needn't be set, surface at the thigh that makes the dihedral supporting mass that is positioned at the flange of rail is matched with under the situation of this surface configuration, this thigh is provided with from the teeth outwards, also be arranged on the surface of the flange of rail, and the thigh that can not cause supporting mass is pressed outward into mesh overlap, because can make the capital stock body absorb the change of shape of elastomeric material by these grooves.Because do not produce outside extruding yet, instantly the inner edge surface of supporting mass is fitted with the contact surface perpendicular to the inside and outside guidance tape at the relevant road junction of guidance tape face, when the thigh of the lower support body that the outer rim of carrying rib is preceding with being positioned at the web of the rail is fitted, supporting mass has good positional stability, in addition, can also be applied in a kind of supporting mass on the rail of different cross section, as long as the cross section of rail has only less difference; Because at cross section is that the strand thickness of supporting mass of dihedral is less, during less than known thickness, desirable needed in other words elasticity in the plane of structure of dihedral supporting member, the possibility of guidance tape width in increasing also is provided, people can be provided with without difficulty above gauge width degree 1.2cm simultaneously, the width 1.5cm that preferably approximately surpasses interior guidance tape, when the shock loading of very big level and vertical stress component occurring, guidance tape moved up in people also can prevent well like this; Guidance tape needn't change track in the installation and removal, what belong to above-mentioned advantageous feature also has, the thigh of dihedral supporting mass can have less thickness, the guidance tape that constitutes the runway of level crossing can obtain good positional stability, and provide bigger than size in the prior art, be positioned at the web of the rail, space in the rail profile, so that the carrying rib is installed, this just might install the interior guidance tape of broad, according to design of the present invention, at the cross section that is positioned on the flange of rail is the upside of the thigh of dihedral lower support body, and between the upside of the downside of the carrying rib of installing on this strand and the flange of rail, being designed to parallelly, this feature is very favourable; This parallel feature just makes the thigh that is positioned at the lower support body on the flange of rail have homogeneous thickness substantially, this parallelism makes that also carrying plane on the rib downside, that be positioned on the lower support body has bigger width, reduce the load on the unit area on the lower support body thus, thereby improved the stability of position; In addition, because according to design of the present invention, can make the thigh of dihedral supporting mass thinner as previously mentioned, and because the trend that the upside of the downside of carrying rib and the flange of rail is parallel to each other makes the carrying rib produce following possibility, promptly carry thickness on the joint location of plate body of rib greater than known situation, thereby strengthened structure, produced bonus simultaneously, promptly in the scope of the carrying rib of road intralamellar part, can install at an easy rate along the reinforcing bar of carrying rib, and on the position of particular importance, i.e. the downside of the carrying of each on guidance tape rib is installed reinforcing bar; Because the strand thickness of supporting mass is less, and has approximately parallel feature at the carrying downside of rib and the upside of the relevant flange of rail according to design of the present invention, for the installation of carrying rib provides sizable space, therefore, people can design the upside of carrying rib deeper and morely, so that the formation flangeway, this flangeway is darker than common, the maintenance that need not at once add the road junction work when rail head wear and tear like this; At last, can obtain following advantage according to approximate parallel between the upside of the downside of the carrying rib of setting of the present invention and the relevant flange of rail, a pith that acts on the power on the guidance tape, promptly acting on the horizontal force that constitutes on the carriageway plate or horizontal component is the flange of rail that the thigh of the lower support body of dihedral is delivered to each rail of track through being positioned at cross section on the flange of rail, so just can reduce to act on the horizontal force on the web of the rail greatly.

According to a particularly advantageous embodiment of level crossing of the present invention, wherein,, it is characterized in that the deep trouth that is provided with forms the groove face each other on the thigh of the lower support body that is positioned at the flange of rail owing to the elastic deformation of supporting mass has fabulous characteristic.

In addition, because the elastic deformation of described lower support body thigh, also be favourable even groove is set at the upside of this strand.For the stress of guidance tape be delivered to power on the rail or the equal advantageous embodiments of load also can be used according to the present invention and conceives the designed accurate bearing that forms the guidance tape of runway in rail, the foregoing description is characterised in that, interior guidance tape comprises that in case of necessity outer guidance tape constitutes two hinged bearing bodies with the supporting mass of the bearing that constitutes them.In addition, people can see, the carrying rib is designed to arc at the upside of carrying rib and the downside of carrying rib at least from its cross section, and this is favourable, and are particularly favourable for the motion of the articulated position of two hinged bearing bodies of transmission power or load.

As mentioned above, if people make full use of according to the given space of design of the present invention to constitute darker edge groove, so advantageously, if people are inboard at rail head and the darker flangeway between the edge of the runway of the interior guidance tape of rail head inboard in, from its dorsad a side of rail head insert a flexible filler, this elastic filler has filled up a part of width of each flangeway, is empty at the flangeway near rail head.If the wheel rim of train is pressed on this filler, this filler when train by the time can be compressed without difficulty by the wheel rim of train; On the other hand, this filler has prevented that heel, vehicle tyre, baby carriage wheel, walking stick and similar item from snapping in.In view of this filler has not only produced a kind of elastic performance, and formed and installing and be rational solution on the life-span, people can see that this filler can be the section bar of being made by rubber or plastics.Also can see simultaneously, the bowl-type protected apron that is provided with on the partial-length of filler is exactly a particularly advantageous embodiment who is provided with the level crossing of this filler, above-mentioned bowl-type protected apron has covered the breach of opening in rail fastening and the interior guidance tape, and this breach is provided with for rail fastening.Be positioned in the guidance tape in covering fully with this method flangeway, invar rail fixture and the breach that is provided with, and it is extremely good fixing that filler is obtained.

People can see, the structure of the interior guidance tape that is provided with according to level crossing of the present invention, and the Load distribution of the production of interior guidance tape and interior guidance tape, and the stressing conditions of guidance tape is favourable in when transportation and installation, guidance tape is consistent along the spacing between the sleeper of rail longitudinal length and adjacent orbit promptly, guidance tape is laid from the sleeper center in each, and setting has the breach of circular concave edge to constitute the space that rail fastening is installed on the angle of interior guidance tape.In this embodiment,, also shortened the carrying rib simultaneously, like this, just reduced for the supporting of guidance tape and locate the danger that epochmaking carrying rib damages common extrahazardous wedge angle rounding in transportation and in installing.This point is particularly suitable for frameless guidance tape, for example, and the common guidance tape of making by the resin concrete.The guidance tape of being made by cement concrete has a metal framework, and following advantage is arranged in the case, and promptly in this framework, the angle with circular concave surface can be than the easier processing of the corresponding breach in the middle part of guidance tape lateral margin.

Be positioned on the flange of rail 10, its cross section is thigh 18 the upside 28 of lower support body 8 of dihedral and the downside 23 approximate upsides 29 that are parallel to the flange of rail 10 of position carrying rib 7 thereon; Equally, the downside of the upside 28a of the thigh 18a of supporting mass 8a and position carrying rib 15 thereon also is in substantially parallel relationship to the upside 29 of the flange of rail 10.Offered numerous continuously arranged deep trouth 31 on the downside 30 of the thigh 18 that is positioned at the lower support body 8 on the flange of rail 10, groove 31 has constituted the groove face each other.

These grooves can make thigh 18 adapt to the shape of the upside 29 of the flange of rail 10 without difficulty, and shape its profile under the loading that guidance tape applied of the thigh 18 of lower support body 8 has only very little change, keeps tabular substantially; Because groove 31 provides the space of the overlap that is used for being contained in the projection 32 of extending between the groove 31.If people also offer groove at the upside of the thigh 18 that is positioned at the lower support body 8 on the flange of rail, as shown in Figure 6, can further strengthen above-mentioned characteristic so.

Because the upside 29 of the flange of rail 10 of rail favours the bearing surface 34 of the rail 5 of the level of being generally usually, therefore, produced the vector component of force of a horizontal applied force with the parallel of the downside that carries

rib

7,15 by the upside 29 of the flange of rail 10, this component of force is represented with arrow 35, the downside 23 that decomposes this horizontal force or force component process carrying rib by power passes to the flange of rail 10, like this, reduced to act on horizontal force on the web of the rail by favourable mode.

As mentioned above, even also can make supporting mass 8 obtain needed elasticity when relatively thin to sink by offering thigh 18 the thickness 36 of groove 31 on being positioned at the flange of rail 10.For this reason, be positioned at rail head 12 belows to the web of the rail 11 both sides, be shaped as the space of the major part of spill, also only highly quite little contact surface 26 need be set for carrying

rib

7,15 provides; 24 places can have big relatively thickness to carrying

rib

7,15 in the installation site, can be directed at carrying

rib

7,15 to reinforcing bar without a doubt, and reinforcing bar 37 is installed in the

guidance tape

3,4, and for example the downside along

guidance tape

3,4 extends.

Fig. 4 uses the section of cutting open by the hatching IV-IV among Fig. 2 to represent to be positioned at lower support body 8 and upper support body 9 on the flange of rail 10.The deep trouth 31 of thigh on 18 upsides 30 that is opened in lower support body 8 constituted a face with groove shape together with the projection 32 of being separated by groove in other words between groove 31.The shape of groove and projection is in view of its elastic characteristic and the crimp that occurs under loading, and under loading, keep strands 18 and profile have good characteristic.Move by can prevent the chance of supporting mass 8 on the flange of rail 10 well in the projection 32 between formed groove 31 and groove and the groove on the downside 30 of thigh 18.Also be provided with projection 32 between this class groove 31 and groove and the groove at the thigh 20 of supporting mass 8 on the thigh 21 of the side of the web of the rail and supporting mass 9 on the side of rail head towards the side of the web of the rail and at thigh 22.Can obtain better elastic and good stickiness and maneuverable superperformance when supporting mass is installed by these grooves and projection.

Fig. 5 uses the section consistent with Fig. 4 to represent another kind of supporting mass 8,9, the groove that is provided with on thigh 18 the downside 30 of supporting mass 8 and constituted the groove face with trapezoid cross section in the projection 32 of groove between groove.This structure has the ability of the bigger big load of opposing or have littler compressibilty under big loading than structure shown in Figure 4.Also be provided with the groove 31 and the projection 32 of same structure at this supporting mass 8,9 towards the outside of residue rail, groove and projection constitute groove together.

The structure of having represented another kind of supporting mass 8,9 in Fig. 6, Fig. 6 uses the section consistent with Fig. 4 and Fig. 5 to represent supporting mass 8,9 once more.Thigh 18 downside 30 at supporting mass shown in Figure 6 is provided with rectangle or dove-tail groove 31 and projection 32, and is provided with groove 38 and projection 39 on the upside 28 of thigh 18.These grooves and projection have constituted the groove face equally.Be provided with this class groove face equally on the surface of the

thigh

20,22 of being close to the web of the rail and the surface of being close to the rail head downside.And people also can be provided with on groove 38 and the upside 28 of projection 39 as thigh 18 set at the

thigh

20,22 that extends along the web of the rail 11 of supporting mass 8,9 towards the sides of carrying rib 7, and these grooves 38 and projection 39 constitute the groove face together.The groove that is opened on strands 18 the upside 28 extends along the rail longitudinal direction.But also can offer the groove 38 of different directions, such as perpendicular to the rail longitudinal direction.

Carrying rib 15 interlockings of outer guidance tape 4 are in supporting mass 8a, by supporting mass 8a outer guidance tape is installed on the flange of rail 10 of rail 5, can have whole corresponding to shape with supporting mass 8 and 9 in order to be used in more applications place supporting mass 8a, as shown in Figure 3.

Fig. 7 embodiment that has represented a railway level-crossing with the corresponding to method for expressing of Fig. 1, in this embodiment, interior guidance tape 3a has constituted a hinged bearing body together with its bearing on the rail 5 of track.In this embodiment, interior guidance tape 3a is designed to act at the vehicle wheel can elastic buckling under the loading on the guidance tape.This load is represented with the arrow among the figure 40.The bending that causes by loading and cause being arranged on the swing of the carrying rib 7a on the guidance tape 3a, as shown in arrow 41.The distortion of guidance tape 3a and carrying rib 7a be with respect to supporting mass 8b, and the swing of 9b has obviously reduced the impact stress to rail and carrying rib that caused by car load.

Fig. 8 is expressed as the fringe area of the guidance tape 3a structure of two hinged bearing bodies settings.Be similar to as shown in Figure 7 edge plane along the edge plane 42 of the carrying rib 7a of rail longitudinal extension, from its cross section, at least be designed to arc at the upper side 43 of supporting rib and downside 44 places of supporting rib, facilitate swing at the bearing position of two hinged bearing bodies like this, edge plane 42 is scabbled a bit according to Fig. 8, and this class guidance tape can be installed in the ready-made rail easily thus.

By above-mentioned possibility-thickness of flexible supporting mass thigh can select relatively forr a short time in the structure of railway level-crossing of the present invention, in the embodiment of Fig. 1 to 3, also used this possibility-can be provided with deeper and morely when needed to the upside 43 of supporting rib, be deeper than side general in previous level crossing, so just produced dark flangeway 45.Because these dark grooves and need not change rail that common need often change or need not be in order to compensate because of the high change of the caused rail of the wearing and tearing of rail head 12 in a long time for thickening the new weldering of rail head.If flangeway 45 is enough dark, allow rail head that considerable wear is arranged so, because of before the necessary maintenance of wearing and tearing, the upper surface 46 that rail head 12 can dot from Fig. 3 arrives the position of representing with 46a such as rail head.Because flangeway 45 is darker than common, therefore, has increased some objects: such as walking stick, narrow heel or its similar item and vehicle enter in the flangeway and are stuck in danger there.In order to eliminate above-mentioned danger, in the embodiment of railway dealings mouth shown in Figure 9, settled flexible filler 47 in a side of the rail head dorsad of flangeway 45, filler 47 has filled up the partial width of flangeway, and the zone of flangeway and rail head adjacency is empty.This class filler 47 is such as being compressible rubber bodies.As shown in Figure 9, particularly advantageous is compressible hollow profile, especially the hollow rubber section bar of installing in flangeway 45 as filler.

Even more advantageously, if people as embodiment shown in Figure 12, have settled bowl-type protected apron 48, this protected apron to cover the fixedly rail fastening 54 of rail 5 on these class filler 47 sides.48 of this protected aprons extend on the partial-length of filler 47.This class protected apron 48 is sealed the breach 52 that is opened in usually in the guidance tape 3, even so that when guidance tape moves also fixing rail fastening 54, thereby the protection rail fastening also can play or help fixedly filler 47.This protected apron 48 fastens the edge of breach 52 and plays fixation in the embodiment shown in fig. 12, and supporting mass 9 has further been strengthened this fixation.This protected apron is preferably made one with the filler 47 in running through flangeway 45, perhaps with the filler integrator.But, also can connect protected apron 48 with other method of filler 47 usefulness, such as adopting gluing or sulfuration.In Figure 13, represented an embodiment who is provided with the filler 47 of protected apron.In this embodiment, on hollow profile 47a, connecting the protected apron 48a of bowl-type, protected apron itself also is to be made by template, its geometrical axis is parallel to the geometrical axis of hollow profile 47a.This class filler can be used quite simple method manufacturing, it is the corresponding to section bar of cross section that people make cross section and hollow profile 47a and protected apron earlier, then, people are from cutting out that part of except the protected apron 48a that will keep with the corresponding to section bar of protected apron.In Figure 14, represented to be provided with another embodiment of the filler 47 of protected apron; In this embodiment, the shape of protected apron 48b is that the shell under shed with straight sidewall is connecting hollow profile 47a at this above the shell, perhaps stick with glue or vulcanize shell and hollow profile are coupled together.The stability of this class shell shape makes filler have good permanent position on the interior guidance tape side of level crossing.

In the railway level-crossing shown in Fig. 1 to 3, interior guidance tape 3 along the longitudinal direction of rail 5 have and the adjacent sleeper of track 2 between the corresponding to length of spacing; Guidance tape 3 is laid between adjacent sleeper center to the sleeper center 51 in each; Offer breach 52 to form the space 53 that rail fastening 54 is installed on the angle of interior guidance tape 3, wherein, breach 52 has the shape edge, garden 55 of a spill.Obtained a kind of guidance tape of form like this, just as explained above, this guidance tape is a kind of impact and not too responsive bearing part of load to occurring in transportation and installation.

In Figure 10, represented another kind of level crossing, in this embodiment, the angle that is provided with guidance tape in making becomes circle, interior guidance tape is always crossed the spacing between adjacent sleeper in the laying state center interconnects, be provided with a space 56 in the carrying rib, this space stops guidance tape to lean against on the rail fastening.The edge 57 of breach 52 is a spill, shown in the vertical view of Fig. 2; People can do the back cutting of basin shape at the downside at this edge if desired.

Guidance tape
